Intention of this series to support multiple download mode and only modify the required bits during setting tcsr register. Other download modes are minidump, full dump, both fulldump + minidump, nodump. Latest minidump kernel driver patches has been sent here https://lore.kernel.org/lkml/1679491817-2498-1-git-send-email-quic_mojha@xxxxxxxxxxx/ Also, this series should be applied on https://lore.kernel.org/lkml/1678979666-551-1-git-send-email-quic_mojha@xxxxxxxxxxx/ Changes in v6: - Applied suggested API change(at v4) by [dmitry.baryshkov] Changes in v5: https://lore.kernel.org/lkml/1680017869-22421-1-git-send-email-quic_mojha@xxxxxxxxxxx/ - Tried to fix the issue reported by kernel test robot https://lore.kernel.org/lkml/202303280535.acb66sQT-lkp@xxxxxxxxx/ - Applied some of the improvement suggested by [Bjorn.andersson] . Dropped 'both' instead support full,mini or mini,full for setting download mode to collect both minidump and full dump. . logging improvement. Changes in v4: https://lore.kernel.org/lkml/1679935281-18445-1-git-send-email-quic_mojha@xxxxxxxxxxx/ - val should be shifted within the function [srinivas.kandagatla] i.e new = (old & ~mask) | (val << ffs(mask) - 1); - Added Acked-by [linus.walleij] on pinctrl change. Changes in v3 : https://lore.kernel.org/lkml/1679070482-8391-1-git-send-email-quic_mojha@xxxxxxxxxxx/ - Removed [1] from the series and sent as a separate patch[2], although this series should be applied on top [2]. [1] https://lore.kernel.org/lkml/1677664555-30191-2-git-send-email-quic_mojha@xxxxxxxxxxx/ [2] https://lore.kernel.org/lkml/1678979666-551-1-git-send-email-quic_mojha@xxxxxxxxxxx/ - Introduce new exported symbol on suggestion from [srinivas.kandagatla] - Use the symbol from drivers/pinctrl/qcom/pinctrl-msm.c. - Addressed comment given by [dmitry.baryshkov] - Converted non-standard Originally-by to Signed-off-by. Changes in v2: https://lore.kernel.org/lkml/1677664555-30191-1-git-send-email-quic_mojha@xxxxxxxxxxx/ - Addressed comment made by [bjorn] - Added download mask. - Passed download mode as parameter - Accept human accepatable download mode string. - enable = !!dload_mode - Shifted module param callback to somewhere down in the file so that it no longer need to know the prototype of qcom_scm_set_download_mode() - updated commit text.
